I am unable to achieve low power after I enable UART. I disabled UART0 after enabling and the UART0 registers are all getting its default value after disabling.
But the current stays at 0.6mA, I even disabled the UART PINs to input floating but still behavior is same. I tried both UART0 and UARTE0 but same behavior.
app_uart_close(); is the API I am using to disable UART.
I have tried a lot of workaround shown in nordic forums but nothing worked for me. I seriously doubt this is some hardware bug and only a chip reset is putting the device into low power.
If I am not using uart_init() then I am able to achieve < 2uA with BLE advertising at 500mS adv interval but due to any reason I enable UART0/UARTE0 ones, then what ever I do, the current is not coming below 0.5mA and I observed the power management loop is halting on no event but this 0.5mA is irrespective of CPU HALT.
I am kind of suspecting this is some hardware issue, if so we have to change the IC.
@Nordic please help
